20000923: sunset downstream sites may feedfrom profhorn.meteor.wisc.edu


Pete,

pqcreate would core dump if you ran out of disk space while trying to create the
queue.....or if creating the queue was excercising some bad disk blocks.
Assuming you have plenty of disk space, you might want to try the format
utility to test the disk for bad sectors - and map them out if found.
